1 Introduction

The PCIe-9529 is a high-performance 8-CH 24-Bit 192 kS/s dynamic signal acquisition module, specifically designed for appli­cations such as structural health monitoring, noise, vibration, and harshness (NVH) measurement, and phased array data acquisi­tion.
The PCIe-9529 features 24-bit simultaneous sampling at 192 kS/s over 8 channels, and a 110 dB dynamic range, providing ample power for high-density, high channel count signal measurement, and vibration-optimized lower AC cutoff frequency of 0.5 Hz. All input channels incorporate 4 mA bias current for integrated elec­tronic piezoelectric (IEPE) signal conditioning for accelerometers and microphones.
The PCIe-9529 is auto-calibrated with an onboard reference cir­cuit calibrating offset and acquiring analog input errors. Following auto-calibration, the calibration constant is stored in EEPROM, such that these values can be loaded and used as needed by the board. There is no requirement to calibrate the module manually.
